Next Fit Algorithm C Program

Let us learn how to implement Next Fit Algorithm in C programming language. The memory management program for Next Fit Algorithm uses Arrays.

What is Next Fit Algorithm?

The Next Fit Memory Allocation Algorithm is also known as Next Fit Bin Packing Algorithm.

This algorithm keeps a track of the positions where every file is written in the memory. It then allocates the very next available memory block to the succeeding processes.

So, when a process is executed to be stored in the memory, the previous bin or the memory block is checked for its availability.

If it is free, then a process is written in the same memory block or else, the next block is checked. This is a very fast searching algorithm and is also comparatively faster than First Fit and Best Fit Memory Management Algorithms.

The Next Fit Page Replacement Algorithm is a modified version of the First Fit Algorithm. It is, therefore, called as Modified First Fit and is faster than the First Fit Algorithm.

While allocating memory blocks, the algorithm begins as the first fit to find a free partition. Next time when the algorithm is called, it starts searching from where it left off, not from the beginning.

Note: This C program for Next Fit Memory Management Algorithm in operating system is compiled with GNU GCC compiler and written in gEdit Editor in Linux Ubuntu operating system.
